    摘要: An electronic control module (10) includes a circuit substrate (12) containing a plurality of thermal vias (36) and a heat-generating electronic device (26) attached to the thermal vias (36). The circuit substrate (12) is attached to a mounting plate (18) by a plurality of electrically-isolated, thermal attachment pads (20) located at selected positions on an electrically insulating layer (16) overlying a metal baseplate (14). A solder layer (22) functions to both mechanically attach the plurality of thermal vias (36) to the plurality of thermal attachment pads (20), and to provide a thermal dissipation pathway for heat generated by the electronic devices (26). The heat is transferred from the circuit substrate (12) through the plurality of thermal attachment pads (20) to the metal baseplate (14).

    摘要: A hermetically sealed interface is constructed with a substrate (101) having a first surface (103) with a first orifice (201). The substrate (101) also has an opposing second surface (105) with a second orifice (205). The first and second orifices (201, 205) are connected via a passageway (107). The passageway (107) has an inner surface (209) with a first metal coating (111). The first metal coating (111) and the substrate (101) provide a first predetermined thermal coefficient of expansion for the passageway (107). A plug (221) with an outer surface (223) has a second metal coating (225). The second metal coating (225) and the plug (221) provide a second predetermined thermal coefficient of expansion substantially similar to the first predetermined thermal coefficient of expansion of the passageway (107). The plug (221) is disposed in the passageway (107) of the substrate (101). The first metal coating (111), of the inner surface ( 209) of the passageway (107), and the second metal coating (225), of the outer surface (223) of the plug (221), are bonded together and provide, with the plug, (221) a hermetic barrier between the first and second orifices (201, 205) of the substrate (101). Preferably, this hermetically sealed interface is used in a capacitive pressure sensor.

    摘要: An improved method and apparatus is disclosed for perpendicularly mounting an AT-strip resonator on its longitudinal edge. The crystal blank is secured to the base at two or more mounting points via conductive cement which provides both electrical connection and mechanical support. A mounting cavity or slot permits proper positioning and self-fixturing during manufacture. The edge-mounting configuration promotes ease of manufacture, improved shock performance, minimized motional resistance degradation, and high packing density.
